This is a quick tip for hiding unreferenced section, elevation and callout tags in a view in Revit 2011:- Go to 'Filters' on the 'View' Tab

- Create a new filter called 'Model Views' and set 'Define Criteria'

- Under Categories, check 'Callouts', 'Elevations' & 'Sections'
- Under Filter Rules, set Filter by 'Sheet Number'. Select 'does not contain' from the drop down box and leave the box under that blank

- Click apply & ok. Now go to the view you want to hide the tags. Go to Visibility/Graphics, select the 'Filters' tab and add the filter. Uncheck the 'Visibility' box and click ok. To switch the unreferenced tags back on, simply go into v/g again and check the box
